Electronic analogue multiplier - uses controlled integration process to improve accuracy, linearity and dynamic range

摘要

The analogue divider is designed to provide increased accuracy, linearity and dynamic range. The reference voltage (UR) is integrated (I1) with the period determined by a control unit that generates an output dependent upon a comparison process. The comparator operates on one of the inputs (U2) and the integrated form of the other input (Uy). The output (UA1) is given by an algebraic function of the voltages, resistances and capacitances.
